The Visbreaking process obtains more valuable lighter hydrocarbons by thermally converting the heavier, less desirable residual oils.  The process can produce a range of issues that need to be addressed, including foaming, corrosion, exchanger fouling, furnace coking and product instability.  Dorf Ketal offers unique chemical programs to address these issues.

We provide:

  • Coking/fouling control in the heaters & preheat exchangers, while maintaining unit conversion rates & throughput
  • Reduced deposition of asphaltenes
  • Stabilization of asphaltenic species in the visbroken tar product
  • Reduced foaming
  • Corrosion control in the fractionator overhead


Delivering profitable, reliable results.
